net: change netdev_hw_addr_list count through helpers

The count of a netdev_hw_addr_list is changed in several places of
dev_addr_lists.c and a few drivers read it directly. The next patch
needs to account every change of the count of dev->mc.

Add __hw_addr_count_add(), __hw_addr_count_inc(), __hw_addr_count_dec()
and __hw_addr_count_reset(), use them for every change of the count
and rename the field to _count so that a direct write stands out.
Readers keep using netdev_hw_addr_list_count() and the netdev_uc_count()
and netdev_mc_count() helpers, the few that read the field directly
are converted. No functional change.
